LUNG-EXERCISER.

Specification of Letters Patent.

Patented Feb. 25, 1919.

Application filed April 6, 1918. Serial N 0. 227,112.

To all whom it may concern:

Be it known that I, CALVIN L. CANADAY, a citizen of the United Statesresiding at Washington, District f Columbia, have invented new anduseful Improvements in Lung-Exerciseraiof; which the following is aspecification. h

,;This inventionrelates tonew and useful i improvements in lungexercisers or trick toys vide' a wheel with means whereby the same willbe 'causedto sing or hum when rotated.

Another object of theinvention is to provide a device of this characterwhich is simpleand durable in construction, reliable and eflicient inoperation and one which can be manufactured and placed upon the marketat a minimum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a perspective view of the invention.

Fig. 2 is a longitudinal section with the parts in one position.

Fig. 3 is a like view with the parts in another position.

Fig. 4 is a section on line H of Fig. 3.

Fig. 5 is a perspective view of the chambered member for controlling thedirection of the air current.

Fig. 6 is a view of a different form of wind wheel.

As shown in these views the invention comprises a block 1, preferablyformed of Wood and having its front face inclined as at 2. The front endof the block is provided with a perpendicular face 3. An upwardlyinclined passage 4 passes through the block from said perpendicular faceto the rear end and this passage is intersected by a large circularchamber 5 extending downwardly through the top of the block. The bottomof said chamber extends below the passage as clearly shown in Figs. 2and 3. The block is also provided with a passage way 6 extending atright angles to the chamber and communicating with its upper end andpassing through the inclined face of the block. 7 indicates acylindrical member having an eccentric chamber 8 therein passingupwardly from the bottom to a point adj acent the upper end of saidmember. The said member is also provided with a pair of holes 9 passinglaterally through its walls and communicating with the upper and lowerportions of the said chamber 8. These openings will aline with thepassages 1 and 6 when the cylindrical member is rotated to bring thechamber 8 toward the front. ofthe device. The cylindrical member is alsoprovided with an inclined slot 10 adjacent its lower end which when thesaid member is in a certain position will connect one part of theinclined passage 1 with the other part, as clearly shown in Fig. 2. Theupper end .of the cylindrical member has opposite sides thereofflattened as at 11 to providea finger hold to facilitate the rotation ofsaid member, said member projects considerably above the top of thedevice so that it may be readily grasped by the fingers.

A tube A has one end inserted in the front end of the passage way 4 andprojects beyond the perpendicular face 3 of the block. The lips of theperson using the device are adapted to be placed against this tube.

12 indicates a pair of arms connected with the sides of the block andprojecting upwardly to provide a support for the wind wheel 13, theshaft 14 of which is journaled in the ends of said arms. As will be seenthe wind wheel is so located that its paddles 15 are located adjacent tothe outer end of the passage way 4 so that the breath of the personusing the device will impinge on said paddles and thus cause the wheelto rotate.

I prefer to provide the paddles with openings 16 to receive metal strips17, which are connected at one end to the paddles with the other endsfree. These strips will act as musical keys so that the wheel will singor hum as it rotates.

Fig. 6 shows a wheel 13 having the plain paddles 15. This wheel may besubstituted for the other wheel so as to reduce the cost of manufactureof the device.

The chamber 8 is adapted to receive flour or other powder and in placingthe powder in the chamber the cylindrical member is held bottom upward.The block 1- is then placed over the member to prevent the powder fromspilling. It being necessary to force the block well down over themember to prevent the powder from getting under the cylindrical member.I may place suitable indicating marks on the cylindrical member and theblock to indicate when the passage way 4: is open and when the opening 9is in register with the passage way '6.

1 When the device is handed to a person un familiar with its operationthe cylindrical member is so disposed that the passage way 4L will beopen so that when he blows into the tube the wheel will spin. The devicemay be then taken away from him and the cylindrical member turned sothat the chamber containing the powder will be in communication with thepassageway 6. Then when he tries to spin the wheel again the powder willbe blown "into his face. The continued use of the device will tend todevelop the lungs, and contests may be held to see which one may spinthe wheel the longest. It is thought from the foregoing descrip tionthat the advantages and novel features of my invention will be readilyapparent.

I desire it to be understood that I may make such changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes 'fall within the scope of the appendedclaims.

What is claimed is:-

l. A device of the class described comprising a member having a chambertherein and a pair of passage ways communicating with said chamber, amouth piece in one of said passage ways and a cylindrical memberrotatably supported in said chamber and having a chamber thereina'daptedto contain powder and provided with a pair ofopenings arranged toregister with the passage ways. I

2. A device of the class described comprising a block having apassageway lpa'ss-' ing longitudinally therethroug h, a mouthpiece inone end of saidpassage way, a wheel located adjacent the other end ofthe passage way, a perpendicular chamber in said block intersectin'gsaid passage way, a second passage way in the upper side of the blockcommunicating with said chamber and a cylindrical member rotatablysupported in said chamber and having a chamber therein adapted to"contain powder and provided with a pair ofopenings arranged to registerwith theep'assagewaysand a slot for connecting the two parts passagewaystoge'ther. v In testimony whereof I affix mysi'gn'ature.
